A long way down 3

What really caught me was, at the end of the book it kind of leaves you with many questions. Such as if they were to ever talk or keep in touch with eath other somehow. If I was in that situation and I met all those people then I would still wanna talk to them dailey just to say hello and how they are doing. Friend like those just stick with you. Another question that I would have is that is all there problems just gone now? Did they learn to deal with all these types of problems?
